ReviewAcute exacerbations of chronic obstructive pulmonary disease.
This article discusses the definition, pathophysiology, cause, clinical presentation, laboratory work-up, and treatment of chronic obstructive pulmonary disease (COPD) exacerbation. The focus is on the presentation of acute exacerbations of COPD in the emergency department and the available evidence for testing and treatment.

ReviewCommunity-acquired pneumonia in the emergency department: a practical approach to diagnosis and management.
Pneumonia is one of the most common conditions for which patients seek emergency care. It is a challenging infection in that the spectrum of illness ranges from the nontoxic patient appropriate for outpatient antibiotics to the critically ill patient requiring intensive care hospitalization. Current data and diagnostic technology provide the emergency physician with the tools for an appropriately rapid evaluation and consideration of the differential diagnosis. ⋯ Although antibiotic-resistant organisms increasingly are being identified, patients continue to benefit from early institution of standard ED treatment. Coverage for atypical organisms improves patient response and outcome. Finally, identification and treatment of the complications of pneumonia and accompanying sepsis must be considered by the ED physician when evaluating critically ill patients.

ReviewManagement of the difficult airway: alternative airway techniques and adjuncts.
Rapid-sequence intubation using conventional laryngoscopic technique remains the standard of airway management in emergency medicine and continues to have a success rate of approximately 98%. Preparation and proper intubation technique must be optimized at the initial attempt using direct laryngoscopy. Failure causes multiple repeated attempts, leading to a failed airway. ⋯ Without proper technique, even with proper positioning, the glottic opening cannot be visualized. Laryngeal pressure to maneuver the larynx into position should be exerted initially by the laryngoscopist's right hand and, when in view, maintained by an assistant to free the laryngoscopist's hand for ETT insertion. With preparation and proper technique, the first attempt is the best attempt, and the vicious cycle of multiple attempts and complications will be averted.

ReviewEvaluation and management of the high-risk orthopedic emergency.
Orthopedic injuries are frequently seen in the ED. Whereas the diagnosis and management of most of these injuries is straightforward, there are distinct pitfalls to avoid. The common theme among the high-risk "pitfall" injuries discussed in this article, besides a thorough patient history and careful physical examination with appropriate radiographs, is a high suspicion for the presence of these injuries. When the EP is knowledgeable about these orthopedic pitfalls, these injuries are much less likely to slip by in clinical practice.

ReviewMedication errors in the emergency department: a systems approach to minimizing risk.
Adverse drug events caused by medication errors represent a common cause of patient injury in the practice of medicine. Many medication errors are preventable and hence particularly tragic when they occur, often with serious consequences. The enormous increase in the number of available drugs on the market makes it all but impossible for physicians, nurses, and pharmacists to possess the knowledge base necessary for fail-safe medication practice. ⋯ A systems approach to the complex problem of medication errors will help emergency clinicians eliminate preventable adverse drug events and achieve a goal of a zero-defects system, in which medication errors are a thing of the past. New developments in information technology and the advent of electronic medical records with computerized physician order entry, ward-based clinical pharmacists, and standardized bar codes promise substantial reductions in the incidence of medication errors and adverse drug events. ED patients expect and deserve nothing less than the safest possible emergency medicine service.
